Troubleshooting Ads txt File Not Found Issue for Google AdSense

If you’re running a website and have integrated Google AdSense to monetize your content, encountering an “ads.txt file not found” issue can be frustrating.

What is Ads txt File?

Ads.txt, short for Authorized Digital Sellers, is a simple, yet crucial, text file that helps prevent unauthorized inventory sales by listing the entities authorized to sell a publisher’s ad inventory.

When this file is missing or cannot be accessed by Google AdSense crawlers, it can lead to disruptions in ad serving and potentially impact your revenue.

Troubleshooting this problem involves a series of steps to locate, create, and properly implement the ads.txt file on your website’s root directory.

This process typically requires accessing your website’s backend, verifying file permissions, and ensuring the correct formatting and content within the ads.txt file.

Additionally, issues may arise due to caching problems, server misconfigurations, or other technical hurdles that prevent AdSense from locating the file.

Addressing the ads.txt file not found issue promptly is essential to maintain a healthy advertising ecosystem on your website, ensuring that authorized buyers can access your inventory and maximizing your revenue potential.

If you’re encountering the frustrating issue of your Adsense showing “ads.txt file not found” even after inserting the code into your theme’s header.php, fear not.

Troubleshooting Process Step by Step

Here’s a comprehensive guide to troubleshoot and resolve this issue effectively.

1. Verify Site Ownership

Before diving into technical tweaks, ensure that your website is approved for AdSense. If not, remove it from your AdSense account and add it again as a new site. Enter your domain name (e.g., “”) and save the changes. This action will trigger site ownership verification.

2. Three Verification Methods

Upon saving, you’ll encounter three verification methods: Adsense code snippet, Ads.txt snippet, and meta tag. Begin by copying the AdSense code snippet provided.

Navigate to your WordPress admin panel and go to the “Appearance” section. From the dropdown menu, select “Theme File Editor” and locate the “Theme Header” or “Header.php” file. Click on it and search for the `<head>` tag. Paste the AdSense code snippet immediately after the opening `<head>` tag on a new line.

4. Meta Tag Verification

After pasting the AdSense code snippet, return to the verification page and select the meta tag verification method. Copy the meta tag provided and paste it immediately after the AdSense code snippet in your website’s code.
